write a lumbda function to formate a name by python

Here's an example of a Lambda function written in Python that formats a name:

import json

def lambda_handler(event, context):
    first_name = event['first_name'].capitalize()
    last_name = event['last_name'].capitalize()
    full_name = f"{first_name} {last_name}"
    return {
        'statusCode': 200,
        'body': json.dumps(full_name)
    }

This function takes in two parameters, `first_name` and `last_name`, which are passed in as part of an event object. It then capitalizes the first letter of each name and combines them into a full name. Finally, the function returns the formatted name as a JSON object with a status code of 200.
